Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag with a removable corner pad.

[0002]

2. Description of the Related Art It is known from experience that the defective parts of a bag such as a document bag which is commonly used for work are a handle for carrying a bag, a clasp, and corners at both lower ends of the front and rear outer surfaces. Since the load of the contents of the bag is applied to the handle, the screw used for attaching the bag to the bag is damaged, and the clasp, which receives mechanical force each time the bag is opened and closed, is worn. Since the functions of these are restored by physical measures such as replacement of metal parts, repair is easy and there is no problem.

However, the corners of the front body and the rear body at the lower ends of the outer surface of the front body come into contact with various hard and soft objects such as furniture, buildings, structures, and human bodies during use of the bag, and wear due to dynamic friction to impair the appearance. . The bag itself is sturdy and long lasting,
If you don't care about the appearance, most of them are still usable. Despite this, if the corners are locally discolored due to abrasion, or if the poly core wire is visible and is thrown away due to its uselessness, it is wasteful of resources only by increasing the amount of waste, which is uneconomical. . On the other hand, repairing this requires a great deal of labor, time, and cost, and becomes a large scale. There is an example of using a fixed angle pad like a nylon case, and even a bag that uses soft leather such as a document bag, the fixed angle pad is preformed and fixed on the corner of the body surface with the same quality leather. There are some that can be seen, but the labor required for repairing this part is slightly reduced, and there is no change in the trouble such as long waiting time and great expense.

[0004]

Therefore, even if discoloration or deformation occurs at the corners at the lower ends of the front and rear outer surfaces of the document bag due to wear, the corner parts can be easily replaced with new parts so that the bag can be easily replaced. The purpose of the present invention is to secure the original life and to effectively utilize the resources.

[0005]

In order to achieve this object, the invention according to claim 1 provides corner pads at corners formed at the lower four corners of the outer surface of the bag by the front body, rear body, gusset and bottom of the bag. It is configured such that it is closely joined, and the joint is detachable.

In order to achieve this object, the invention according to claim 2 is such that the corner pad has a curve formed by a trunk plane forming the corner portion of the bag and a bottom and a gusset adjacent to the trunk plane being continuously formed. It is formed by three-dimensionally integrally molding so as to be in close contact with the surfaces, and an adhesive tape (male type) is sewn to the close surfaces.

In order to achieve this object, the invention according to claim 3 is characterized in that the close-bonding is performed on a body plane forming the corner portion of the bag and a curved surface continuous with the bottom and the gusset adjacent to the body plane. The adhesive force between the sewn adhesive tape (female type) and the adhesive tape (male type) sewn on the flat surface and the curved surface of the contact surface of the corner pad, respectively. is there.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a relationship between a bag (1) and a corner pad (2) according to a first embodiment of the present invention, and FIG. 2 shows a situation in which the corner pad (2) is joined to the bag (1). FIG. The bag (1) is normally used in the state shown in FIG. The bag (1) shows a document bag on the figure, but it is common for the hand to be swung back and forth when walking with the hand in hand, so the corner (10) of the bag (1) hits an object and is worn out. Or In that case, the discoloration of the corner portion (10) can be easily repaired by replacing the spare corner pad (2), and the use of the bag (1) can be continued.

The bag (1) is mainly made of leather, a core material and an adhesive tape, and a front body (11-1), a rear body (11-2) and a center body in the first embodiment by using a pattern paper or a die. The through gusset pieces (12-1) and the balls (13) for partial connection were cut into the required shapes and subjected to the required processing, and then each member was sewn to finish. The same applies to the corner pad (2). FIG. 3 is an explanatory view showing the shape of the front body (11-1) for the bag (1), the rear body (11-2), the symmetrical gusset piece (12-1) and the ball (13) after cutting. Fig. 4, Fig. 4 is an explanatory view showing the state of making the through-gusset piece (12-1) of the body (11), and Fig. 6 is an explanatory view of the procedure of sewing each member into a bag. is there. As described above, in the first embodiment, the through gusset piece (12-1) is used by being connected to the central portion, but when the size of the bag (1) is large or it is not convenient to cut leather. In this case, the left gusset (12-7), the bottom gusset (12-5), and the right gusset (12-
7) Divide into 3 parts and cut these 3 parts.
The bag (1) is finished by stitching it to 1-1) and the back trunk (11-2).

The front body (11-1) and the rear body (11-2) of the body (11) are slightly different in vertical length due to the relationship of the metal fittings, but their shapes are almost the same. The method of making it varies depending on the type of leather used for the body (11), but if it is hard, the whole is first made to be 1.6 to 1.7 mm, and if it is soft, it is 1.8.
~ 1.9 mm solid strainer, and kip (6 months to 2 years old cowhide), goat (goat leather) or pig leather with a thin leather itself, attach a core such as felt to the leather itself to bring out the thickness. To use. Hard leather was used in the first embodiment. Therefore, first, filter the whole by 1.6 ~ 1.7 mm,
Next, the corner forming edge (11-3) and the upper opening edge (11-
4) was passed through the helicopter, and the edge of the sewn part (11-5) with the thread (12) was passed through. The situation is shown in FIG.

By arranging two through gusset pieces (12-1) symmetrically and connecting them at the central portion, a through gusset (12) having an integrated gusset and bottom can be obtained. Through gusset piece (12-
1) First, the whole is cut by 1.4 mm, and then the edge of the corner forming part (12-2) and the edge of the metal fitting attaching part (12-3) are put back by helicopter, and the front body (11-1) and the rear part The edges (12-4) of the sutured portion with the body (11-2) were beaded. In addition, Sashimi for the partition and the central connecting part were sewn. The situation is shown in FIG. Further, the balls (13) were used by being long-tied together and strained.

The corner forming portion (11-6) to be sewn to the quarter forming edge (11-3) of the body (11) has an adhesive tape (female type) after cutting adhered thereto. In addition, a split circle-shaped corner forming portion (12-4) was also obtained by the same procedure. This corner forming part (12-4) is sewn to two corner forming part edges (12-2), and two through gusset pieces (12-1) are arranged symmetrically, and there is a slit (12-5). The two pieces were connected at the sides to pass them to obtain a gusset (12). Front torso (11-1)
The gussets (12) are placed on top of each other, and together with the ball leather (13) with the poly core (14) sandwiched between them, the front body (1
The sides AB, BC, and CD of 1-1) and the side EH of the through gusset (12), that is, EF, FG, and GH were sewn together so as to overlap each other. The other opposite sides of the threaded gusset (12) were sewn in the same manner. Then, by carefully returning the outer leather to the outside, a bag as a bag in which an adhesive tape (female type) is sewn to the corner portion (10) of the bag can be roughly formed.

In the first embodiment, the corner forming portion (11-6)
Although the shape is formed into a quarter circle at the edge (11-3) of the corner forming portion of the body (11), any other shape can be used. For example, the scalene triangle (Fig. 7), 4
It is arbitrary such as a 1 / oval shape (FIG. 8), a shape in which the arc center of a 1/4 circle is evenly cut (FIG. 9), or another shape. When the shape of the corner forming portion (11-6) of the body (11) is changed from the quarter circle shape to another shape such as an isosceles triangle (FIG. 7), the shape of the corner forming portion (11-6) is The shape corresponds to it. An example thereof is shown in FIG.

FIG. 11 is a front view of the corner pad (2), FIG. 12 is a plan view thereof, FIG. 13 is a bottom view thereof, FIG. 14 is a right side view thereof, and FIG. 15 is a rear view thereof. In FIGS. 11 and 13, the surface indicated by a broken line for convenience is an adhesive surface of an adhesive tape (male type). The corner pad (2) is formed by sewn together the quarter-radius portion of the corner pad surface (2-1) and the straight portion of the corner pad bottom (2-2) to integrate both members into a right angle shape. The adhesive surface of the adhesive tape (male type) is formed on the inner surface thereof. The planar shape of the corner pad surface (2-1) that constitutes the corner pad (2) is formed in a shape corresponding to the shape of the corner forming portion (11-6) that is in close contact with it.

16 to 18 are explanatory views showing a process of forming the corner pad (2). The corner pad (2) is mainly made of leather, core material, and adhesive tape (male type), like the bag (1). These materials are first cut, and then the shape, thickness and the like are adjusted to improve functionality, finish and the like. The corner padding leather (21), which is one of the parts for forming the corner padding (2), is cut into a quarter circle shape, and then 1.2 mm solid is squeezed using a large shaving machine. 1.6 cut into a circle
mm Strain. Strained leather and adhesive tape (male type) cut into split circles are squeezed around them with an edge machine. For the core material, remove the patch of the square pad core (23) with the back side of Este 0.6 patch processing, and attach the leather embossing core (24) with a smaller area and a similar shape to the felt patch at the center. . Further, the patch of the leather lift core (24) is peeled off, and it is attached to the center of the corner pad leather (21). The leather and the core are crimped, and the leather is raised to make it look up, and it is decided with a lever. Apply a T-bond adhesive to the leather and core with a glue knife and flip the leather back along the core. Since the curved part is raised by the return of leather, hit it with a hammer to flatten it. Cut off excess portions with scissors, apply a roller to press the leather, and obtain a square padding leather (21).

There are various types of core materials used for the above-mentioned square pad core (23) processed by the emblem 0.6 patch and the leather raised core (24) processed by the felt patch. Soft core materials include sponges, felts, pefs, esthetics, clavos, slicers, etc., and hard core materials include contex, vontex, texon, and other floor leathers.
The corner pad (2) with different feeling can be made by combining the core materials. For example, if a sponge was used instead of the felt embossed leather heap core (24), it felt more elastic and soft, but I decided that it was not necessary to put it up to that point, and I chose a felt and esthetics. There are various types of adhesives as well, including T-bond, rubber glue, banjaku, cybinol, U-board, CR bond, diamond bond, etc. T-bond was adopted in consideration of adhesiveness.

The corner pad bottom leather (22), which is to be combined with the corner pad surface leather (21) to form the corner pad (2), is formed by the following steps. After cutting it into split circles, stick double-sided tape on the back side of the adhesive tape (male type) that was strained around
Attach it to the corner padding leather (22). Adhesive is applied to the arcuate edges and the leather is pulled back using a linen or scraper.

For the back side of the adhesive tape (male type) to be attached to the corner pad bottom leather (22), the core portion on the back side of the corner pad bottom leather (22), and the leather making portion on the back side of the corner pad bottom leather (22). An adhesive is applied and a wooden mold or a mold stand (5) is prepared separately. An adhesive tape (female type) is attached to the side of Control 2 of the mold stand (5). The square taped adhesive tape (male) (25) is placed on the upper surface of the mold table (5) with the back side facing up. Corner leather (2
1) is attached to the side surface of the mold stand (5), the part protruding above is edged back, and a double-sided tape is attached to the edged part. The corner pad bottom leather (22) is stuck on this, removed from the mold stand (5), and the front part of the mouth and the back part of the mouth are glued to complete the adhesive body of the corner pad (2). Sew the adhesive connection on the outside with the arm sewing machine, sew it on the inside with the post sewing machine, cut it with the thread sandwiched, and if the thread is Vinimo, lightly heat it to stop the thread and complete the corner pad (2). To do. The thread used for suturing includes natural fiber silk thread, artificial fiber thread such as tetron, vinylo, vinylon and nylon, but vinylo was selected in consideration of strength, workability and appearance.

FIG. 19 is a perspective view showing the relationship between the bag (1) and the corner pad (2) of the second embodiment. As described above, in the first embodiment, the corner portion (1) of the document bag as an example of the bag, particularly the Dulles bag having a relatively soft body, gusset, and bottom is used.
Although the case of applying to 0) has been described, depending on the type of Dulles bag, there is a case where the body is a hard flat surface and the gusset and the bottom do not form a curved surface. That is, when a portion corresponding to a curved surface formed by the gusset and the bottom is forcibly searched for on the side of the bag on which the corner padding leather (22) contacts, the gusset and the bottom stitched portion in the corner (10) of the trunk (11) are close to each other. There is only the thickness of the body. If the width of the bottom of the corner padding leather (22) is narrowed to the thickness of the body, there is no room to attach an adhesive tape (male type) here. However, by narrowing the width of the bottom of the corner padding leather (22),
It can also be used for polishing and hem-backed bags other than ball bags. In the case of this bag, since the adhesive tape (female type) is not attached to the gusset, the adhesive tape (female type) of the front and rear trunk angle forming portion (11-6) is the adhesive tape (male) of the square padding leather (21). It is closely bonded to the mold). As a result, the corner pad leather (2
The inward horizontal movement of 1) on the body surface is restricted, and the purpose of protecting the corner of the bag can be achieved only by the corner padding leather (21).

In the present invention, cow leather was used, but in addition to cow leather, leather such as horse, pig, crocodile and snake, woven fabrics such as canvas, denim and jacquard, vinyl chloride leather, and synthetic leather and artificial leather. It can be carried out using a chemical product place. When nylon, cloth or thin leather is used as the material of the body (10), the corner forming portion (11-6) is not cut in order to secure the strength. From the same idea, the corner forming edge (12-2) of the gusset may be left without being cut. The situation is shown in FIG.

[0021]

According to the detachable bag with the corner pad according to the first aspect of the present invention, even if the lower end corner portion of the document bag is discolored and deformed due to abrasion due to use, the portion can be easily replaced with a new part. However, not only can the original life of the bag be secured and effective use of resources can be achieved, but by changing the color of the leather, the fashionability will be further enhanced and the demand will be increased. Therefore, it is possible to save useless labor for repairing the bag,
There is no need to sew or sew when repairing, difficult work such as color matching between the repair surface and the entire surface of the bag body is avoided, and it is not necessary to go to the bag store to request and collect the bag, and it is completed. There is no need to wait for a long time, and it is possible to save a great deal of money required for restoration and to expect an increase in demand.

According to the detachable bag with the corner pad according to the invention of claim 2, the corner pads which are in close contact with the trunk plane of the corner portion of the bag and the curved surface formed by the gusset and the bottom adjacent thereto,
The bag can be used while protecting the corners of the bag and maintaining a sense of unity by closely contacting the bag. Even if the corners of the bag wear and discolor, etc., the parts can be easily replaced with new parts. Can be replaced, saving a great deal of labor, time and money required for repair. Therefore, it is possible to save unnecessary work labor for repairing the bag, do not need to unsew or sew during repair, and avoid difficult work such as color matching between the repair surface and the entire surface of the bag.
